An apparatus and process for forming particles.

A method for reducing water consumption in a toilet system comprises adding a water-soluble pellet to the toilet bowl prior to or following use of said toilet for urination, the pellet comprising a colourant and a fragrance for masking the colour and odour of urine residing in the toilet bowl, and preferably also disintegrant and/or an effervescent system that effervesces on contact with water, and refraining from flushing said toilet until after said toilet has been used at least one further time. The use of such water-soluble pellets serves to reduce the perceived need to flush the toilet after every use and drives positive change against wasteful water usage. The pellets are small, for example 8 mm or less in diameter and weigh 0.1-0.3 g, and can be stored in a re-sealable, refillable, reusable dispenser for personal or larger scale use. The method also serves to reduce carbon emissions and chemical usage arising from treatment of fresh and waste water.

A process for forming particles. The process includes a step of entraining gas into a precursor material, wherein the gas includes from about 50 vol % to about 75 vol % carbon dioxide and from about 25 vol % to about 50 vol % other constituents. The precursor material is deposited onto a moving conveyor. The precursor material is cooled to form a plurality of particles.
